The Chairman of Montgomery County Republican Committee, Bob Kerns, abruptly resigned his position late Thursday afternoon.

Sunday during a Montgomery County GOP breakfast many on the committee learned what sources have confirmed to Action News that Kerns is being investigated for a sexual assault.

Robert Kerns officially resigned as the chairman of Montgomery County's Republican Committee.

In a statement released by the executive director Thursday, they announced the acceptance of his resignation, but said they have "no comment on media reports related to a possible criminal investigation of Mr. Kerns unrelated to his duties as chairman".

Kerns is also a lawyer and a partner at Kerns, Pearlstine, Onorato and Hladi.

Sources tell Action News the victim alleges the assault currently being investigated happened October 25th.

Montgomery County Commissioner and former District Attorney Bruce Castor released a statement saying: "While this is another sad day for the Montgomery County Republican Committee, we will come out of it stronger than before. I urge people not to speculate, and let law enforcement do their work."

Sources say Kerns last job as chairman was to call a special meeting for December 4th where a new chairman will be selected.
